The distant expanded steel-core aluminium wire with the structure has smooth surface and can prevent the surface of the wire from forming ices.
Description
Technical field
The utility model relates to a kind of naked aerial condutor, specifically is a kind of anti-ice and snow steel reinforced aluminium conductor.
Background technology
Plain conductor is in ultra-high-tension power transmission line, because its surperficial electric field strength height, anti-corona poor performance, in corona discharge, also follow high-frequency noise, radio interference, even conductor galloping takes place, the economic benefit that causes transmitting electricity descends, therefore must the electric field strength of conductive line surfaces be limited, generally should make the maximum functional field intensity of conductive line surfaces be no more than 90% of whole corona field intensity, to avoid producing visual corona.Reach this purpose, preferably can adopt expanded conductor.In the previous ultra-high-tension power transmission line of producing, adopted the lead of hollow expanded conductor or metal hose hole enlargement, but its intensity is low, corrosivity is poor, joint quality is not high, useful life is short.
In addition, occur in various places during the hazard weathers such as sleet and sleet, lead will break because sleet is avenged the influence of weight.Sometimes even electric pole in a row, iron tower are forgotten about it, telecommunication and transmission of electricity are interrupted, produced for resident living and enterprise and bring massive losses.Particularly the regional this phenomenon at awful weathers such as big river valley, mountain area, plateaus is particularly serious.
Various on the market at present conductive line surfaces are coarse, the slit is bigger, and therefore sleet and the snow that drops on the lead can be attached in the slit between the lead, and the center of gravity of lead is partial to a snowy end thereupon, and lead produces a moment thus.Because the coefficient of torsion of this kind expanded conductor is lower, this means that the remaining less sleet of conductor side is enough to make lead itself to produce and reverses, cause the lead rotation, thereby make snow (ice) ball that covers on the lead roll more and more, form the cylinder icing on its surface.Along with constantly gathering of icing, cause collapsing of electric pole and iron tower the most at last, telecommunication and transmission of electricity are interrupted.
The utility model content
Technical problem to be solved in the utility model is the above-mentioned defective at existing various steel reinforced aluminium conductors, and a kind of anti-ice and snow steel reinforced aluminium conductor that prevents that frost from covering is provided.
The technical scheme that solution the utility model technical problem is adopted is this anti-ice and snow steel reinforced aluminium conductor, comprise steel core, be overlying on the outer outer aluminum steel layer of steel core, on the cross section of described outer aluminum steel layer, fit tightly between every adjacent in twos aluminium single line, after all aluminium single lines were superimposed, the outer surface of outer aluminum steel layer constituted a smooth disc.
Outer aluminium stranded conductor can be one or more layers.
Preferably, in the described outer aluminum steel layer, the shape of cross section of each aluminium single line is trapezoidal, and the shape of each aluminium single line, size are all identical, and after all aluminium single lines were superimposed, whole outer aluminum steel layer constituted an annulus.
Further preferably, on the cross section of described outer aluminum steel layer, the contact-making surface between every adjacent in twos aluminium single line is the snap-latch surface that fits tightly, and the shape of each aluminium single line, size are all identical, after all aluminium single lines were superimposed, whole outer aluminum steel layer constituted an annulus.The cross section of each aluminium single line forms snap-latch surface, can prevent to produce between the adjacent in twos aluminium single line dislocation.Adopt the aluminium single line of this cross sectional shape can be " Z " shape or serpentine or "T"-shaped.
The utility model prevents in the ice and snow steel reinforced aluminium conductor having between steel core and the outer aluminum steel layer and dredge around hole enlargement aluminum steel layer, dredges can be one or more layers around hole enlargement aluminum steel layer.
Guarantee that the aluminum steel gap is even, the layer of every adjacent aluminum steel layer with layer between direction of lay opposite, and outermost aluminum steel layer direction of lay is dextrad.
Steel core can be that single steel core also can be stranded steel core.If adopt stranded steel core, the direction of lay of steel core can be left-hand or dextrad.
Advantage of the present utility model is as follows: have high strength, corrosion-resistant, joint quality is high, long service life, the electric field strength of conductive line surfaces is low, avoided corona discharge, little to wireless interference, that the elongation permanent deformation little and lead of wriggling of moulding after laying is installed is little, characteristics such as lightweight construction.And more level and smooth, solid, compact than conventional wires, it can use the wire clamp identical with conventional wires to install, and its effective cross-section is bigger under the situation identical with the conventional wires diameter, can carry higher electric current; Its damping characteristic is better, can bear the vibration that strong wind etc. causes; Reduced vertical vibration and improved the characteristic of turning round shake, especially under the lower situation of vibration frequency, significantly reduced any owing to wave the wearing and tearing to corollary equipment of generation.Because do not have the space between the twisted wire, so the noise that corona effect produces is also littler, natural precipitation can will wash away totally attached to the dust on the electric wire like a cork, has reduced noise and line loss.Because outer aluminum steel layer forms a smooth circumferential surface, significantly reduced snow and frost gather and ice and snow is deposited on caused huge moment of torsion on the electric wire, can successfully manage bad weathers such as sleet.

Embodiment
The anti-ice and snow steel reinforced aluminium conductor of the utility model comprises steel core 1, is overlying on the outer outer aluminum steel layer 4 of steel core, on the cross section of described outer aluminum steel layer 4, fit tightly between every adjacent in twos aluminium single line, after all aluminium single lines were superimposed, the outer surface of outer aluminum steel layer 4 constituted a smooth disc.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Following examples are indefiniteness embodiment of the present utility model.
Embodiment 1:
As shown in Figure 1, steel reinforced aluminium conductor from inside to outside is followed successively by internal layer and is dredged around hole enlargement aluminum steel layer 2, middle level thin around hole enlargement aluminum steel layer 3, outer aluminum steel layer 4 by stranded steel core 1 and its three outer stranded forming of aluminum steel layer in the present embodiment steel core 1 outside.Wherein, internal layer is dredged and to be dredged around hole enlargement aluminum steel layer 2 and middle level around hole enlargement aluminum steel layer 3 to dredging around stranded, and outer aluminum steel layer 4 is for closely stranded.
